Gossan Valley copper/zinc project, Australia – update
Name of the Project
Gossan Valley copper/zinc project.
Location
South of the existing Gossan Hill mine, in Western Australia.
Project Owner/s
Copper-focused base and precious metals company 29Metals.
Project Description
Gossan Valley is expected to enhance overall ore production and scheduling flexibility by providing an additional independent, and relatively shallow, production front at Golden Grove mine, an established mining operation that started production in 1990.
Gossan Valley will produce 4 000 t/y of copper and 20 000 t/y of zinc over an initial seven-year mine life.
Access to the project will be from a central boxcut located near the Gossan Valley deposit, with a decline to access Grassi deposit and a separate decline accessing the Gossan Valley and Conteville deposits. The mining method will be conventional longhole open stoping with mining methods, and rockfill, where possible, to minimise waste brought to surface.
Potential Job Creation

Net Present Value/Internal Rate of Return
The project has an estimated net present value of $110-million and an internal rate of return of 34%.
Capital Expenditure
$112-million.
Planned Start/End Date
